Journal Title:Bonfring International Journal of Industrial Engineering and Management Science

The present paper deals with some new modified ratio estimators for estimation of population mean using the quartiles and its functions of the auxiliary variable. The bias and the mean squared error of the proposed estimators are obtained and are compared with some of the existing modified ratio estimators. As a result, we have observed that the proposed modified ratio estimators perform better than the existing modified ratio estimators. These are explained with the help of numerical examples.
